Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a pleated shade.

[Prior art and its problems] Conventional pleated shades have a problem in that light leaks from the insertion hole of the shade operating string that passes through the shade member and is connected in the opening/closing direction, resulting in incomplete light shielding. Was.

Furthermore, conventional pleated shades have had the problem that the pleats do not open uniformly. In particular, when used in a place that opens and closes in the vertical direction, there is a problem in that due to the weight of the shade member, the upper folds are wide and the lower folds are narrow, resulting in an unsightly appearance. Further, even with pleated shades that open and close horizontally, the pleats on the movable box side open widely, while the pleats on the fixed box side open narrowly, resulting in an unsightly appearance.

The applicant previously filed a registered utility model No. 1025648 (Registered Utility Model No. 1025648) for an accordion-shaped Venetian blind that maintains an accurate opening between the folds when unfolded and can be moved up and down in a straight state. Publication No. 48-17502) was obtained.

The present invention is an improvement on the previous invention, and solves the above-mentioned problems, allowing light to be blocked not only in vertical pleated shades but also in horizontal, slanted, and curved pleated shades. To provide a pleated shade which can be made complete, have an accurate opening between pleats when unfolded, has a simple structure, and can be manufactured at low cost.

[Means for Solving the Problems] In order to solve the above problems and achieve the purpose of the invention, the pleated shade according to the present invention is characterized by having the following structure. That is, a tape is attached to the shade member as a shielding material for the insertion hole through which the shade operating string is inserted, which is continuous in the opening/closing direction, and the tape and the shade member are made of a material that can be welded to each other, and the shade member Tapes are welded to the tops of all the shade members on one side at appropriate intervals, and the tapes are provided with folds that are folded toward the shade members at approximately the center of the spacing between the tops of the shade members, and when the shade members are opened, the tapes are welded at appropriate intervals. is folded toward the shade member side and stored, and the tape at the stored portion does not come into contact with the operating string.

[Example] The present invention will be explained in detail below using an example shown in the drawings. Fig. 1 is a perspective view of one embodiment of the pleated shade according to the present invention, Fig. 2 is a partially cutaway plan view,
3 is a side view of the same, FIG. 4 is a partially cutaway sectional view when the shade member is closed, and FIG. 5 is a partially cutaway sectional view when the shade member is opened. here,
1 is the shade member, 11 is the top of the shade member, 1
Reference numeral 2 indicates a shade operating string, 13 indicates an insertion hole, 2 indicates a tape, and 21 indicates a fold of the tape.

The pleated shades according to the present invention include vertical ones, horizontal ones, inclined ones, curved ones,
Including both. The embodiment shown in the drawings is an embodiment in the vertical case.

In the present invention, a tape 2 is also provided as a shielding material for the insertion hole 13 of the shade operation string 12 which is connected in the opening/closing direction. In this embodiment, there are two shade operation strings 12. An insertion hole 13 for a shade operating string 12 is provided in the shade member 1, and a narrow band-shaped tape 2 is provided as a shielding material to completely shield the pleated shade from light.

In the present invention, the tape 2 completely blocks light from the pleated shade, and also regulates the opening of the shade member 1 by adjusting the opening between the folds, which is the top 11 of the shade member 1, at the time of unfolding. The tape 2 is joined to all the shade member tops 11 on one side of the shade member 1 at appropriate intervals, and when the shade member 1 is opened, the tape 2 is folded to the shade member 1 side and stored. It is formed. In this embodiment, the tape 2 is bonded to the entire top portion 11 of the shade member.

The stored tape 2 is formed so as not to come into contact with the operating string 12. When the shade member is opened as shown in FIG.
Since the tape 2 does not come into contact with the operating string 12, the tape 2 and the operating string 12 are prevented from coming into contact with each other when opening and closing the pleated shade, thereby preventing the tape 2 and the operating string 12 from being worn out or broken.

In this embodiment, the tape 2 is provided in advance with a pleat 21 that is folded toward the shade member 1 at approximately the center of the interval between the shade member tops 11. The folds 21 are the tape 2
It is possible to provide in advance the pleats 21 that are folded toward the shade member 1 side by directly applying the pleats 21 to the tape 2 or after processing the tape 2 with resin. By forming in this way,
The folds 21 are reliably folded.

The joining length of the tape 2 and the top part 11 of the shade member may be the length of the full width of the tape 2,
Alternatively, a part of the width of the tape 2 may be joined. In either case, it is sufficient that the tape 2 is formed so as to enter into the shade member 1 side, and the joining length between the tape 2 and the shade member top portion 11 can be set to an appropriate length. By forming it in this way, when the shade member 1 shrinks, the tape 2 is folded and stored on the shade member 1 side, so the tape 2 does not protrude from the shade member 1 and the tape 2 does not get in the way. It can be used without any problems.

The shade member 1 and the tape 2 are made of materials that can be welded together, such that they can be simply and easily welded using a welding machine such as an ultrasonic welder. Therefore, the shade member 1 and tape 2 are made of fibers of thermoplastic resin such as polyester or nylon.
Formed from film or nonwoven fabric. By forming it in this way, it can be manufactured simply and easily, and therefore can be manufactured at low cost.

[Effects of the invention] Since the pleated shade according to the present invention is configured as described above, it is possible to block light not only in vertical pleated shades but also in any pleated shades such as horizontal, inclined, and curved ones. In addition to making the pleats perfect, even when unfolding, the pleats can be opened accurately, providing a pleated shade with a beautiful appearance.Moreover, it has a simple structure and can be manufactured at low cost. has.
